PURPOSE OF REVIEW Sandfly fever viruses are still a significant health problem in many regions of the world, such as Africa, the Mediterranean basin, the Middle East, and Central Asia. This review provides an update on the advances in knowledge about epidemiological, clinical, and laboratory aspects of infections caused by Toscana, Sicilian and Naples(More)
The role of Toscana (TOS) virus in producing encephalitis without meningitis is uncertain. We studied 2 cases of TOS virus encephalitis without meningitis by means of nested polymerase chain reaction assay and DNA sequencing. Findings confirm that TOS virus may directly cause encephalitis and suggest the usefulness of DNA sequencing in investigating(More)
Mycobacterium genavense is a frequently missed agent of disseminated disease in AIDS patients. The increasing frequency with which such organism is being isolated in Italy suggested a comparison of local survey with data reported in literature. Isolates presumed to belong to the species M. genavense were centralized and identified by means of genomic(More)
Two strains of the newly proposed species "Mycobacterium genavense" have been isolated, using the radiometric system (Bactec, Becton Dickinson), from the blood of two HIV-infected patients. Disseminated infections due to the new organism closely resemble those of the Mycobacterium avium complex, with prevalently intestinal symptomatology. We report here on(More)
A case of non-fatal encephalitis in a 21-y-old immunocompetent woman is described. High titre serum antibodies against Mycoplasma pneumoniae were found. In addition, Mycoplasma pneumoniae DNA was detected in the cerebrospinal fluid by polymerase chain reaction. Neuroimaging findings by magnetic resonance and computed tomographic scanning of the brain, and(More)
A case of chronic intestinal infection due to adenovirus type 40 lasting for 13 months in a patient with AIDS is described. Adenovirus particles were detected by electron microscopy in biopsy samples taken from the duodenum 3 months after the onset of diarrhoea. The virus was identified as adenovirus type 40 in stool samples by ELISA monoclonal antibodies(More)
AIMS To investigate changes in morphology of the developmental stages of Enterocytozoon bieneusi and symptomatic relief observed in AIDS patients after treatment with furazolidone. METHODS Six AIDS patients with symptomatic E bieneusi infection of the small intestine were treated with a course of furazolidone. All patients had a weekly monitoring of(More)
The efficacy of furazolidone for treatment of intestinal microsporidiosis due to Enterocytozoon bieneusi was studied in three patients with AIDS. All patients had chronic diarrhoea and weight loss. Mean CD4 cell count was 34.6/mm3. A course of furazolidone (100 mg orally four times a day) was given for 20 days. The drug was well tolerated and neither side(More)
